Why is it better? At St. Bernards, we're always looking for the latest technologies that will provide the earliest detection. Digital mammography has been shown to be especially effective in doing so in women under the age of 50 and those with particularly dense breasts. Studies have found the technology to be superior for overall image quality, skin and nipple depiction, pectoral muscle depiction and the detection of small calcifications. Benefits to the patent include shorter exam times and a decrease in the number of the lost films.
